Constructor Detail

ButtonScrollingCanvas | () | Constructor

`public function ButtonScrollingCanvas()`

Method Detail

addChild | () | method

`override public function addChild(child:DisplayObject):DisplayObject`

If we have already created the innerCanvas element, then we add the child to that. If not, that means we haven't called createChildren yet. So what we do is add the child to this main Canvas, and once we call createChildren we'll remove all the children and switch them over to innerCanvas.

Parameters

| `child:DisplayObject`

Returns

| `DisplayObject`

addChildAt | () | method |

`override public function addChildAt(child:DisplayObject, index:int):DisplayObject`

Parameters

| `child:DisplayObject`
| `index:int`

Returns

| `DisplayObject`

createChildren | () | method |

`override protected function createChildren():void`

enableOrDisableButtons | () | method |

`protected function enableOrDisableButtons():void`

We check to see if the buttons should be shown. If we can't scroll in one direction then we don't show that particular button.

getChildAt | () | method |

`override public function getChildAt(index:int):DisplayObject`

Parameters

| `index:int`

Returns

| `DisplayObject`

getChildByName | () | method |

`override public function getChildByName(name:String):DisplayObject`

Parameters

| `name:String`

Returns

| `DisplayObject`

getChildIndex | () | method |

`override public function getChildIndex(child:DisplayObject):int`

Parameters

| `child:DisplayObject`

Returns

| `int`

getChildren | () | method |

`override public function getChildren():Array`

Returns

| `Array`

initialize | () | method |

`override public function initialize():void`

updateDisplayList | () | method |

`override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void`

Parameters

| `unscaledWidth:Number`
| `unscaledHeight:Number`
